Resumo: | The efficient model preparation allows a crop forecast, better research strategies and the correct allocation of a determinate crop in an environment, according to weather conditions. With the techniques uses as the modeling, it is possible to create future scenarios using simulations, which use equations to represent a process. To achieve the high agricultural productive, there is a necessity to identify the production factors that limit the plants growth. The most part of the years, the rain frequency and its intensity in the soybean development period aren t enough to a crop shows its productive potential. So, the present research has as a purpose the application of a simulation model to the soybean crop in the region of Santiago RS, allowing to know the production response of many different water lengths. To accomplish the job it was necessary to develop an experimental proceeding to generate necessary datas to calibrate, test and apply a simulation model of water extraction from the soil and its respective response in the crop production. As experimental results, it was obtained variation in the growth and soybean crop development with the application of many different irrigation strategies, resulting in distinct productivities. The increase in the irrigation length provided an increment in the production components of the studied crops. The production model applied was able to simulate satisfactorily the total dry matter and the grain production to the soybean crop. The water balance components were influenced by different simulated irrigation strategies, and these influenced in the final productivity of the crop studied. The efficiency of the water use and the efficiency of the water application became less with the irrigation strategies increase. The production model application to the production functions showed that, the applied length since 800 mm caused a reduction in the production of soybean crop grains. The model showed itself as an important tool in the productive preview in irrigated conductions, showing the best strategies of irrigation that result in a high grain production. |

A partir da utilização de técnicas como a modelagem, é possível a criação de cenários futuros por intermédio de simulações, que utilizam um conjunto de equações que irão representar um processo. Para se alcançar altas produtividades agrícolas, há necessidade de se identificar os fatores de produção que limitam o crescimento das plantas. Na maior parte dos anos, a freqüência e a intensidade das chuvas no período de desenvolvimento da soja, são insuficientes para que a cultura manifeste seu potencial produtivo. Desta forma, o presente trabalho propõe a aplicação de um modelo de simulação para a cultura da soja na região de Santiago, RS, permitindo conhecer a resposta da produção a diferentes lâminas de água aplicada. Para isto, foi necessário desenvolver procedimento experimental para geração de dados necessários para calibrar, testar e aplicar um modelo de simulação da extração da água do solo e a respectiva resposta em produção da cultura. Como resultados experimentais, obteve-se variações no crescimento e desenvolvimento da cultura da soja com a aplicação de diferentes estratégias de irrigação, resultando em produtividades distintas. O aumento nas lâminas de irrigação proporcionou incremento nos componentes de produção das cultivares estudadas. O modelo de produção aplicado foi capaz de simular satisfatoriamente o acúmulo de matéria seca total e a produção de grãos para a cultura da soja. Os componentes do balanço hídrico foram influenciados pelas diferentes estratégias de irrigação simuladas, e estas influenciaram na produtividade final da cultura em estudo. A eficiência do uso da água e a eficiência de aplicação da água diminuíram com o aumento da estratégia de irrigação. A aplicação do modelo de produção para funções de produção mostrou que, lâmina aplicada a partir de 800 mm causou redução na produção de grãos na cultura da soja. O modelo se mostrou uma importante ferramenta na previsão da produtividade em condições irrigadas, evidenciando as melhores estratégias de irrigação que resultem em elevadas produções de grãos.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia AgrícolaUFSMBREngenharia AgrícolaEstratégias de irrigaçãoModelo de produçãoSimulaçãoIrrigation strategiesProduction modelSimulationCNPQ::CIENCIAS AGRARIAS::ENGENHARIA AGRICOLAEstudo experimental e simulado da cultura da soja em função de diferentes níveis de irrigaçãoSimulated and experimental study of the soybean crop due to different levels of irrigationinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisRobaina, Adroaldo Diashttp://lattes.cnpq.br/8629241691140049Peiter, Márcia Xavierhttp://lattes.cnpq.br/4072803412132476Parizi, Ana Rita Costenarohttp://lattes.cnpq.br/8175867178097138Costa, Paulo Roberto dahttp://lattes.cnpq.br/2335007069922943Schons, Ricardo Luishttp://lattes.cnpq.br/9875030355020810http://lattes.cnpq.br/6321874855275614Gomes, Ana Carla dos Santos500300000008400300300300300300300a461031e-e4dd-4408-ac4e-e2eea463cc61c9036432-e80f-4932-81d3-eb2c34540bbd6cff507b-c590-4711-88ff-f4923a065e43d7863e73-bc55-4751-866c-bc07b63624d9cd0ca4b7-25f8-4530-a49d-32d171b6e93a7d1e571a-da90-4fe7-8d75-e4ac591a55e0info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALGOMES, ANA CARLA DOS SANTOS.pdfapplication/pdf2462314http://repositorio.ufsm.br/bitstream/1/3589/1/GOMES%2c%20ANA%20CARLA%20DOS%20SANTOS.pdf23f93ec505f95b1f09cfc889123b2836MD51TEXTGOMES, ANA CARLA DOS SANTOS.pdf.txtGOMES, ANA CARLA DOS SANTOS.pdf.txtExtracted texttext/plain285789http://repositorio.ufsm.br/bitstream/1/3589/2/GOMES%2c%20ANA%20CARLA%20DOS%20SANTOS.pdf.txtd84f6f49da719fb4804d2ad2debaca43MD52THUMBNAILGOMES, ANA CARLA DOS SANTOS.pdf.jpgGOMES, ANA CARLA DOS SANTOS.pdf.jpgIM Thumbnailimage/jpeg4981http://repositorio.ufsm.br/bitstream/1/3589/3/GOMES%2c%20ANA%20CARLA%20DOS%20SANTOS.pdf.jpg93962a93d596a0fa52f4e2cbd11ae0e1MD531/35892022-01-12 08:59:21.2oai:repositorio.ufsm.br:1/3589Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132022-01-12T11:59:21Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
